USB support
The base subsystem is implemented on the main processor board and uses the
core USB support that is provided by the system-board chip set. SurePOS 700
Models 723, E23, 743, C43, E43, 783, E83, 784, C84, and E84 support the USB
1.1. and 2.0 standard. All system board USB controllers are Universal Host
Controller Interface (UHCI) and Enhanced Host Controller Interface (EHCI)
compliant.
Unique software interface
For the software programmer, the SurePOS 700 appears as a PCI-based PC
system unit with the usual PC peripherals. The unique POS function is packaged on
the PCI riser card. The system unit also provides the following unique functions:
v
128 KB of nonvolatile random access memory (NVRAM)
v A ROM bank that connects to the system ROM during power-on self-test (POST)
to provide additional functionality and information
v
An interface to the RS-485 (Electronic Industries Alliance [EIA] 485) subsystem, if
the system is equipped with RS-485 ports
1
v
An interface to the POS USB subsystem
